Weighing only 30g (1.1 oz), the Motus Hat provides exceptional moisture management and effective sun protection during hot weather mountain training and racing. The light, airy Phasic™ SL fabric utilizes multidimensional polyester yarns to wick and disperse moisture for rapid evaporation. The weave allows a high rate of airflow for cool comfort. A lightweight brim offers added sun protection, a soft insert at the forehead improves comfort, and the keyhole cutout in the back aids airflow and accommodates a ponytail. Adjustable fit.
